Boardwalk Empire

Premiered: Sunday, Sept. 8, at 9 p.m. on HBOStars: Steve Buscemi, Michael Shannon, Michael K. Williams, Jeffrey WrightWhat to expect: Nucky Thompson may have won last season’s war, but there’s no rest for the wicked. With the emergence of increased racial tensions, the introduction of Harlem gangster Valentin Narcisse (Jeffrey Wright), and the rise of that G-Man of G-Men, J. Edgar Hoover, things won’t be easy. Buscemi says: ”He’s attempting to keep a lower profile, be out of the public eye more, which is not easy for him because I think Nucky really enjoyed being the politician, being out there and mixing it up.” —Keith Staskiewicz
